Apparently a short description is 'Man's wife goes blind, he builds robit to help her continue writing, everyone begins noticing, starts asking for robit to help them with their issues, then military notices and get interested in applications for war'.

As someone who used to a huge fan of the series, they need to but a bullet in its head and put it down. Every iteration after Hollow Ataraxia (Zero is the only exception) has had less love and care put into it. The magic that made the series great at the start is now gone.

I'll still state that I'm bitter that the true route was never finished due to time constraints (Ilya's route). It was supposed to explain how Shirou ends up losing everyone close to him and descends into the jaded world view that he is later now for as EMIYA. Ending finally with him becoming exactly like Kiritsugu, with him killing a few people to save thousands. Sadly, it spawned a war in his effort to save people. One of the people he saved was the one who pushed for EMIYA to be punished, which is how his death originally happens. Of course, that got retconned because they screwed themselves over in their writing.

The route was supposed to be a divergent of Heaven's Feel and be significantly darker, namely due to the death of a majority of the characters.
